Is this bag large enough to carry my BC, Reg, Fins, Mask, Etc...?
Also, filled with the same gear, could I use it as a carry on bag?
Monica s Depending on your equipment, if you have basic recreational items it should fit what you list just fine. Here are the dimensions 68x39x23cm. Whether this would work as a carry on really depends on the airline restrictions, you have to check with them.
